Ref Aunt Beru’s food mixer sound effect.

It seems that when the Lars homestead was ransacked the food mixer being of the highest quality was taken by storm troopets. Once put into the empire’s storage facilities it came up on a database of desireable pillage list items and Tarkin spotted it and figured he could do with one in the control roon of the deathstar in case he got a bit peckish whilst destroying planets and such. 😃

The sound efffect is indeed labelled “Aunt Beru’s food processor” but it can be heard in the control room in the battle of yavin at one point…
